<h3>What is weight?</h3>
The weight of matter is found as the product of the mass and the gravitational acceleration.
Unit conversion;
1 lb =0.45 kg.
Dosage of a drug = 200 mg / kilogram
John weighs = 80 lb
1 lb =0.45 kg.
80 lb = 36 kg

The tools that were used by ancient mathematicians to make geometric constructions are compasses and straightedges. A compass is a drawing instrument used to draw circles and arcs. The straightedges on the other hand is a tool to check on the accuracy of a straight line.
The answer is first choice.
We can write an equation of this, with p representing the unknown population. We know that 90% of the population owns cars:
90% * p
We also know that 4761 people own cars, which is the same as the above expression, so we write:
90% * p = 4761.
From there, you just divide both sides by 90%, or 0.9
p = 4761/0.9 = 5290
The population is 5290 people.
Expenses of respondents in a survey is a quantitative data and the level of measurement is a ratio scale.
<h3>What is a Qualitative and a Quantitative Data?</h3>
